In this regard, where is Ozone located in Earth's atmosphere quizlet?

It is found naturally in the earth's stratosphere, where it absorbs the ultraviolet component of incoming solar radiation that could be harmful to life on earth.

Subsequently, question is, why is ozone important in the atmosphere quizlet? Stratospheric ozone is important in the earth system because it absorbs ultraviolet radiation from the sun, protecting life on earth. Ozone is a relatively rare and unstable molecule composed of three oxygen atoms O3. This layer of the atmosphere is made up of five layers of gases, especially oxygen and nitrogen.

One may also ask, what is ozone in the atmosphere?

Ozone is a gas made up of three oxygen atoms (O3). Ozone protects life on Earth from the Sun's ultraviolet (UV) radiation. In the lower atmosphere (the troposphere) near the Earth's surface, ozone is created by chemical reactions between air pollutants from vehicle exhaust, gasoline vapors, and other emissions.

Where is the ozone layer located and what does it do?

The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains high concentration of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.

What is the origin of oxygen in Earth's atmosphere quizlet?

Earth's early atmosphere contained only small amounts of free oxygen, probably produced entirely by the reaction of sunlight with water vapor from volcanoes. The oxygen-rich atmosphere that evolved later, and upon which oxygen-breathing life now depends, was a result of the origin of photosynthesis.

Which part of the atmosphere contains the highest concentrations of ozone?

Most ozone (about 90%) is found in the stratosphere, which begins about 10–16 kilometers (6–10 miles) above Earth's surface and extends up to about 50 kilo- meters (31 miles) altitude. The stratospheric region with the highest ozone concentration is commonly known as the “ozone layer” (see Figure Q1-2).

How was the Earth's atmosphere formed quizlet?

Theory 1a: Gases which formed the earth's early atmosphere were released from volcanoes. oceans formed when water vapour condensed as earth cooled down., and fell as rain. As icy comets rained down on the surface of the earth, they melted, adding water. This produced oxygen gas as a 'waste' product!

How does the atmosphere protect life on Earth quizlet?

How does the Atmosphere protect life on Earth? The Atmosphere protects and contols the temperature on the surface of the Earth. It absorbs or reflects the radiation from the sun; and the "Greenhouse Effect" helps to control the temperature on Earth.

What are all the reasons why Earth's atmosphere is important to life on Earth?


Answer 1: The atmosphere is important for many reasons! One reason is that the earth's atmosphere acts as an insulating layer that protects the earth's surface from the intense light and heat of the sun. The atmosphere is also important because it contains oxygen, which we and other living organisms breathe.

What happens to the atmosphere as you travel away from Earth?

As you travel away from the Earth's surface, the atmosphere expands the further you go. As the atmosphere expands the further you get from the Earth's surface, it becomes less dense and air pressure decreases. As you increase altitude (distance from Earth's surface) in an airplane, air pressure changes.

What is the most significant fact about the oxygen in Earth's atmosphere quizlet?

Oxygen forms about 20 percent of the earth's atmosphere, and is the most abundant element in the earth's crust, mainly in the form of oxides, silicates, and carbonates. Argon is the most common noble gas, making up nearly one percent of the earth's atmosphere.

What layer of the atmosphere is the most vital for supporting life on Earth quizlet?

The thermosphere absorbs solar radiation and helps to regulate the Earth's temperature. All layers of the atmosphere are important for supporting life on the Earth, but the troposphere is the most important as it provides organisms with the air they breathe..

How is ozone generated?

Ozone is produced naturally in the stratosphere when highly energetic solar radiation strikes molecules of oxygen, O2, and cause the two oxygen atoms to split apart in a process called photolysis.

How many ozone layers are there?


Ozone is mainly found in two regions of the Earth's atmosphere. Most ozone (about 90%) resides in a layer that begins between 6 and 10 miles (10 and 17 kilometers) above the Earth's surface and extends up to about 30 miles (50 kilometers). This region of the atmosphere is called the stratosphere.

Are ozone machines harmful?

Whether in its pure form or mixed with other chemicals, ozone can be harmful to health. When inhaled, ozone can damage the lungs. Relatively low amounts of ozone can cause chest pain, coughing, shortness of breath and, throat irritation.

What does ozone layer do?

The ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (UVR) from the sun, protecting life on Earth from its potentially harmful effects. When the sky is clear, there is an inverse relationship between stratospheric ozone and solar UVR measured at the Earth's surface.

How is ozone helpful?

Ozone is a gas in the atmosphere that protects everything living on the Earth from harmful ultraviolet (UV) rays from the Sun. The ozone layer acts as a shield to absorb the UV rays, and keep them from doing damage at the Earth's surface.

How is ozone destroyed?

When ultraviolet light waves (UV) strike CFC* (CFCl3) molecules in the upper atmosphere, a carbon-chlorine bond breaks, producing a chlorine (Cl) atom. The chlorine atom then reacts with an ozone (O3) molecule breaking it apart and so destroying the ozone.

What is o3 called?


Ozone is a natural gas composed of three atoms of oxygen. Its chemical symbol is O3. It is blue in color and has a strong odor. Normal oxygen (O2), which we breathe, has two oxygen atoms and is colorless and odorless. Environmental scientists have classified O3 into two: Good Ozone and Bad Ozone.

Is there a hole in the ozone layer?

The ozone hole occurs during the Antarctic spring, from September to early December, as strong westerly winds start to circulate around the continent and create an atmospheric container. Within this polar vortex, over 50 percent of the lower stratospheric ozone is destroyed during the Antarctic spring.

How damaged is the ozone layer?

Ozone Depletion. When chlorine and bromine atoms come into contact with ozone in the stratosphere, they destroy ozone molecules. One chlorine atom can destroy over 100,000 ozone molecules before it is removed from the stratosphere. Ozone can be destroyed more quickly than it is naturally created.
